Well, got up to the first Check and Alignment Section and then ran into a problem.The LED display does not work. I suspect U1 which is the microcontroller chip that controls practically everything on the PCB. Taking a break from the whole project and will get back to it in a few days. I have troubleshoot it for several days now and can’t find anything wrong. I can’t vouch for U1 without replacing it…so will have to order it and see if that fixes it.
